Cubiertas móviles

La construcción convencional suele plantear soluciones fijas para la mayor parte de los elementos básicos. Los requerimientos funcionales de algunos programas pueden adaptarse mejor a soluciones cambiantes. Para ello pueden optar por la solución de la cubierta móvil, que no se halla muy difundida y se describe en el presente artículo.

Canonical Homotopy Operators for @ in the Ball with Respect to the Bergman Metric
Andersson, Mats; Ortega Cerdà, Joaquim
We notice that some well-known homotopy operators due to Skoda et. al. for
the $\bar\partial$-complex in the ball actually give the boundary values
of the canonical homotopy operators with respect to certain weighted
Bergman metrics. We provide explicit formulas even for the interior values
of these operators. The construction is based on a technique of
representing a $\bar\partial$-equation as a $\bar\partial_b$-equation on the
boundary of the ball in a higher dimension. The kernel corresponding to
the operator that is canonical with respect to the Euclidean metric was
previously found by Harvey and Polking. Contrary to the Euclidean case,
any form which is smooth up to the boundary belongs to the domain of the
corresponding operator $\bar\partial^*$, with respect to the metrics we
consider. We also discuss the corresponding $\bar\square$-operator and its
canonical solution operator.
Moreover, our homotopy operators satisfy a certain commutation rule with
the Lie derivative with respect to the vector fields
$\partial/\partial\zeta_k$, which makes it possible to construct homotopy
formulas even for the $\partial\bar\partial$-operator.
